Benefits of technology
[0009]Exemplary embodiments of the present invention provide a method of supplying power capable of extending a discharge time of a battery.
Problems solved by technology
However, solar energy has a low energy converting efficiency, and as a result, utilization of solar energy technology may include a large setup size.
Further, power obtained using solar energy may be unstable depending on the strength of received sunlight and the incident angle of the received sunlight.
However, since standard batteries have characteristics similar to a capacitor, a charging operation and a discharging operation are not simultaneously performed.

A power supply apparatus includes a storage battery, a power part and a solar battery part. The storage battery provides a charged voltage to an electronic device. The power part provides an external voltage to the electronic device and simultaneously charges the storage battery, upon determining that the external voltage is provided to the power supply apparatus. The solar battery part charges the storage battery using a voltage output by a solar battery upon determining that the external voltage is not provided to the power supply apparatus and the electronic device is not in use, and provides the voltage output by the solar battery and the charged voltage output by the storage battery to the electronic device, upon determining that the external voltage is not provided to the power supply apparatus and the electronic device is in use.
